GSH to Provide HVAC Repairs, Replacement, Maintenance, and New Installation
November 17, 2014
GSH Group Inc., a multi-national facilities and energy management provider, announced that it has been awarded a three-year contract with the New York City Department of Correction. The contract, valued at over $2.7 million, is for HVAC services at various department facilities.
Two combustion analyzers, models 310 and 320, can be used by HVAC techs for residential tuning and commercial applications. The 310 is a residential analyzer designed to measure flue gas, draft, ambient CO, and pressure, while the 320 is for residential and commercial boiler/burner tune-ups, service, and maintenance.
Bob and Tim have arrived at a “no cooling” call at a commercial building location. They went first to the thermostat and noticed that the indoor fan was running, but there was no cool air coming out of the air registers.
Bob and Tim have been sent on a call to a house with no cooling. The system has just been installed and the construction crew has been having problems with startup. The system has a capillary tube metering device and Bob and Tim begin looking at what may be wrong.
Bob and Tim were on their way to a residence where the occupants said their unit runs all day long, but the space temperature rises to 82°F while the thermostat is set at 75°. The unit shuts off during the night and the temperature inside is 75° in the morning, but during the day it rises.
Bob and Tim were on their way to a no cooling call at a commercial building. When they arrived, they talked to the building manager and checked the thermostat. It was set at 72°F but the thermometer was reading 78°. Tim said, “The fan is running, so there is control voltage and the thermostat seems to be calling for cooling.”
Bob and Tim were just finishing a service contract call when they were contacted by the dispatcher about a no cooling call at a new installation at a small retail store. The weather was unusually warm for this time of the year.
